The Mark Morris Dance Company’s annual residency at Tanglewood has developed into one of the more collaborative projects ever undertaken at the New England music center. “The unique aspect of the Tanglewood project is that the musicians – singers and instrumentalists alike – learn Morris’s choreography as well; they learn to put the music into their bodies in a different way. They not only rehearse one movement of the music they will be playing; they actually perform it, for an invited audience of staff, friends, and fellow students.”
